It may not be brutal, but it's pretty damn savage 
oh yeah its savage..
but so is electrucuting someone..most so..
beaheading looks savage = deterent
electrocution = zapping EVERY damn pain receptor in your body..takes a LONG time to die
beaheading ..you die quick..(unless done slowly..Iraqi taliban style)
btw ..most of the low class in saudi is pakistani immigrants..
another side note..my mum ws once buying jewelery in saudi..when it ws prayer time..the shop owner just up n left..left the jewellery sitting right there on the country..told mum he'd be back and in the meantime she could try on anything she wanted ..
brutality WORKS..i'm for it...
